Rays with endpoints and vectors.
Although a ray is isomorphic to a SurfaceVertex3D
, it does not have the
same behavior.
projectRay :: RSdouble -> Ray3D -> Point3DSource
The parametric function of a ray. The parameter is measured as a
proportion of the length of the vector. projectRay 0
is the
endpoint of the ray. projectRay 1
is the endpoint offset
by the ray's vector.
distanceAlong :: Ray3D -> Point3D -> RSdoubleSource
The inverse operation to projectRay
. This could also be
understood as the height of the point above the plane defined
by the ray.
angleFrom :: Ray3D -> Point3D -> AngleSource
The angle between vector of the ray and the vector from the endpoint of the ray to the specified point.
normalizeRay :: Ray3D -> Ray3DSource
A ray normalize to a length of 1.
